对于图$F$和$G$,令$F\to(G,G)$表示$F$的任何红/蓝边着色包含单色$G$。定义Folkman数$f(G;p)$为图$F$的最小阶,使得$F\to(G,G)$且$\omega(F)\lep $。证明了$f(G; p)\le cn$,其中$\Delta(G)\le \Delta$,$c=c(\Delta)$,$p=p(\Delta)$是正常数。
For graphs $F$ and $G$, let $F\to (G,G)$ signify that any red/blue edge coloring of $F$ contains a monochromatic $G$. Define Folkman number $f(G;p)$ to be the smallest order of a graph $F$ such that $F\to (G,G)$ and $\omega(F) \le p$. It is shown that $f(G;p)\le cn$ for graphs $G$ of order $n$ with $\Delta(G)\le \Delta$, where $\Delta\ge 3$, $c=c(\Delta)$, and $p=p(\Delta)$ are positive constants.
